What is the minimum radius to run the Shay engine product # 82903? Previous product # incorrect.
82903 is a 3 Truck Climax.....not a Shay.
Either way.....both will run on 18 inch radius curves with no effort. With a little tweaking, 15 inch is possible as well. The Climax is a little better suited for the tighter radii because of it's central driveline. The Shay can open up it's driveline on a sharp left hand bend.
